Yesterday, Crikey reported that the High Court’s decision to grant a retrial to Jean Gassy, the man accused of killing the former head of South Australia’s mental services, Margaret Tobin, “is sending shockwaves: through the SA police and legal community, as well as the medical profession and health administrators across the country”.

There should be no shockwaves at all. The High Court was merely untangling a glaring and serious error made by Justice Ann Vanstone, a high profile South Australian judge who presided over Mr Gassy’s 2004 trial. The judge failed to give Mr Gassy what he, like every one else, is entitled to expect – a fair trial.
